I have an 01 Mustang and I also have Eibach lowering springs. Well I have hit a couple of speed bumps and torn up the passenger side BANK 2 converter so the check engine
light came on. I called the Ford dealership to get it replaced and they wanted about $2,300 just to replace the CATS. I thought this was ridiculous so I went to the muffler shop and the CAT he had was way to thick. So I need some help on places to get good prices. Also if you cut a CAT off and run a straight will it cut down on HP?
